[need help] about examples in ESP-DL (AIV-621)

[fatsheep2020]

here my 2 question:

1. the examples "cat_face_detect", "color_detect", ..., was running in ESP32, not see what's the model details, how to know that? (例子中的模型是开源的吗，哪里有介绍吗？)

2. for a specific use case, how to setup/train a model target for ESP32S3? what's the constraint? (针对ESP32建立、训练模型有哪些限制（模型太大肯定跑不动），有哪些需要注意的地方？ 请乐鑫技术人员给解释一下吧，这样便于我们开发人员做二次开发）

THanks!
